Trichloroacetic acid (TCA)
TCA can be used in many concentrations, but it’s most commonly used for medium-depth peeling. Fine surface wrinkles, superficial blemishes, and pigment problems are commonly treated with TCA. The results of TCA peel are usually less dramatic than (and not as long-lasting as) those of a phenol peel. In fact, more than one TCA peel may be needed to achieve the desired result. The recovery from a TCA peel is usually shorter than with a phenol peel.
With a TCA peel, your healed skin will be able to produce pigment as always—the peel will not bleach the skin. However, TCA peel patients are advised to avoid sun exposure for several months after treatment to protect the newly-formed layers of skin. Even though TCA is milder than phenol, it may also produce some unintended color changes in the skin.
